===Location===
*Nasal cavity - rhinitis
*Paranasal sinuses - sinusitis
*Guttural pouch and eustachian tube - eustachitis
*[[Pharynx - Anatomy & Physiology|Pharynx]] - pharyngitis
*Trachea - tracheitis
*Bronchi - bronchitis
*Bronchioles - bronchiolitis
*Lungs - pneumonia/pneumonitis
*Pleura - pleuritis/pleurisy

===Type===

Grossly many inflammatory processes (eg: response to viral or bacterial infection) in the URT will begin as a serous discharge, and then progress to a catarrhal exudate, and then to purulent/pseudomembranous/haemorrhagic as neutrophils are recruited

*Serous - transparent fluid exudate (acute inflammation)
*Catarrhal - mucous exudation (acute to subacute inflammation)
*Pseudomembranaous - fibrin exudation
*Purulent - pus
*Ulcerative
*Haemorrhagic
*Granulomatous (chronic inflammation)
*Polypoid (chronic inflammation)

===Timecourse===
*Acute
*Subacute
*Chronic

===Causes===
*Infectious agent
